.To all 'whom 'it may concern.

Be it known that I, PETER V. TAMIETTI, a citizen of the United States, residing at Monrovia, in the county of Los An bles and State of California, have invente a new and useful Signal for Vehicles, of which the following is a specification.

My invention relates to a signal for inotor vehicles of the class adapted to give notice that the vehicle is about to turn.

An object of my invention is to provide a signal of this class which will readily discernible from some distance at night or in the day time. i

Another object of my invention is to provide a signal of this character which can A be readily affixed to a vehicle at a point conl veniently accessible for the operator of the vehicle.

Another object of this invention is to provide a signal of this class which will be of a simple construction and durable and sure in operation. l

ln the drawin Figure 1 is a plain view of my signal with one of the signal arms in extended position.

Fig. 2 is a vertical section of the same.

Fig. 3 is a detail illustrating the method of attaching my signal to the frame of a vehicle.

Fig. 4 is a section taken on line indicated by w-w*, Fig. 2.

Fig. 5 is a diagram illustrating the electric circuit used in the si al.

Referring to the drawings, there is represented at 1 a cylindrical hollow shell. Mounted within the shell 1 are two. cylindrical hollow tubes 2, each of a diameter equal to approximatelvone-half of the diameter of the shell 1. The tubes 2 are closed at one end by a wall 3 and are inwardly threaded at their opposite ends 4.

Each of the tubes 2 is provided with a longitudinal hollowr rod 5, which rod is provided at one` end with a collar 6, the collar 6 being preferably screw-threaded onto the end of the rod 5 and of a diameter corresponding to the inner diameter of the tube ,2. Mounted at the end of each of the tubes 2 is a coil sprin 7 which is ada ted to abut against the co lar 6 of the ro 5 and tend to force the rod 5 from without the tube 2. The threaded end 4 of the tubes 2 is closed by a cap 8 screw-threaded therein, which cap is apertured to slidably en- `gage the rod 5. The rod 5 is of a reater ength than the tube 2 and is provided at its outer end with signal means com rising an electric lobe 9 having a soc et 10 mounted Iwit in thev tube and a uiird 11 surroundin the globe 9. In addition to the electric glo e 9 the end of tlie rod is provided with a fla si al 12 ada ed for use particularly in t e ay'Y time. he flag signal 12 comprises a cloth ,13 secured to the rod 5 and the guard 11 and to a wire- 14 which-.is bent in a double vane surroundin the guard 11. A flat extensible spring 1 surroundsand registers with the wire 14 and is'secured at its ends to the rod 5. The sprin 15 is provided with clips 16 to retain t e rod 14.

The-collars 6 are provided with arms 17 which are slidablyreceived Within lon is tudinalslots 18 formedvixi the shell 1, which slots are providedwithbayonet extensions 19 at their ends and the arms 17 are formed with convenient handles 20.

The circuit for the electric lobes 9, as indicated at Fig. 5, is formed y the sockets 10 contacting with the edge of the rods 5 forming a ground. Wires 22 lead from the globe 9 through the rods 5 and are connected to the contacts 23 which are mounted in the collars 6, the contacts 23 projecting slightly from the collars and the collars 6 being preferably of insulating material. Secured to the caps 8 within the tubes 2 are bushings 24 in which are mounted contacts 25 spaced to register with and contact with the contacts 23 when the springs 7 are in extended position. The contacts 25 are provided with connections 26 which extend Without the shell 1. From the connections wires 27 lead to one terminal of a switch 28. The opposite terminal of which switch is connected to one terminal of a battery 29. The opposite terminal of which battery is grounded as illustrated in Fig. `5.

The tubes 2 are preferably secured within the shell 1 by set screws 30 and the shell l is adapted to be secured to the frame preferably adjacent the steering wheel of the vehicle by means of a bracket 31, as illustrated in Fig. 3.

The operation of the signal is as follows: The shell 1 is of alength approximately equal to the Vwidth of the vehicle. When the vehicle is being operated along a straight road the arms 17 are secured within the bayonet extensions 19. The springs 17 are exerting a tension against the col ar 6 which tends to slide the rod 5 through the cap 8 and extend the end of the rod and signal means without the shell 1. If the operator of the vehicle intends to turn, he grasps one of the handles 20 and moves the arm 17 from without the bayonet extension 19. The rod will be freed and the spring 15 will slide the rod through the cap 8 until the collar 6 abuts the bushin 24. As the signal end of the rod leaves t e shell 1 the spring 15 carring the cloth 13 will expand,

forming a dou le vane which acts as a warning that the vehicle is about to close and when the rod 5 is in an extended position the contacts 23 and 25 will complete the circuit and the globe 9 will be illuminated.

After the vehicle has made the turn the operator will gras the handle 20 and return the arm 17 to the ayonet extension 19 from which it was originally released. This will be accompanied by a compression of the spring 7 and the rod will be withdrawn within the shell 1. As the spring 15 enters the shell 1 it will abut against the edge of the shell and the edge of the opposite tube 2 and will be contracted as illustrated in Fig. 2 of the drawings.

It is understood that the two rods rovide for signaling that the vehicle is a out to turn to the right or to the left. If the vehicle is to be turned to the left one of the handles 20 is operated as above described and if it is to be turned tothe right the other handle 2O is sc operated.

My invention is not limited to the details of construction heretofore described, but is of the breadth and scope set forth in the subjoined claims.

I claim:

1. A signal for vehicles comprising a shell, two tubes superposed within said shell, each of said tubes 4being provided with a signal carryin rod, means Within said shell to ,project sai signals from without said shell, and slots in said shell receiving means to operatively control said rods.

2. A signal for vehicles comprisingl a' ell shell, tubes superposed within said s having one of their res ctive ends closed, rods mounted in each o said tubes, collars upon said rods, caps for said tubes apertured. to slidably receive said rods, spring means mounted between the ends of said tubes and said collars to force said tubes from without said shell, and signal lmean carried by said rods. l

3. A signal for vehicles comprising a shell, rods slidably mounted within said shell, means to extend said rods from said shell, means to control the movement of said rods, electric globes carried by said rods, means to illuminate said globes, and vanes carried by said rods surrounding said globes, said vanes being surrounded by an extensible sprin means;

4. n a signal for vehicles the combination of an elon ated shell, tubes superposed Within said Shel-Kl having one of their respective ends closed, rods mounted Within said shell and adapted to project therefrom, sigfnal means carried bv said rods, collars upon said rods slidably received Within said tubes, springs mounted between said collars and the ends of said rods adapted to propel said rods into extended position, slots formed in said shell, arms carried by said rods slidably received Within said slots, bayonet extensions of said slots adapted to receive said arms to secure said rods in retracted position against the action of said springs, and caps mounted at the ends of said tubes and Slidably receiving said rods to limit the extended .position of said rods.

Signed at Los Angeles, California, this 28th day of March, 1919.
